Neither of the BSD ports to Xen (FreeBSD and NetBSD) have domain zero 
functionality (at this time). I don't think there are any plans to 
implement domain zero functionality for NetBSD, I don't know what the 
FreeBSD guys are intending to do.

That should work in principle. Xend configuration files should allow you to 
specify what domain to use as a backend for a device. I'm not sure anybody 
has actually ever tried it...
